Yeah its possible, but it'd be a hybrid snake if she were ever to lay eggs.
Theres alot of mixed thoughts on hybrids, mostly negative ones.
Also, they're called Carpalls.
Its also not a good idea to house ANY 2 snakes together for any reason other than breeding. The reason they're staying coiled around each other is for competition for the best spot in the enclosure. Please rethink about re-housing them in they're own enclosures.
